Republican-aligned Crossroads GPS has added California's GOP-held 36th district to its target list for television advertising spending over the final weeks of the campaign.

The group is spending a total of $2.2 million on TV this week across nine districts, part of an $8.1 million investment in 11 House races that it announced last week. The addition of Rep. Mary Bono Mack's (R-Calif.) district increases that number to 12 and is further confirmation that the Palm Springs-based district is one of the top battlegrounds in the country.
